Does improved oral hygiene alone prevent ventilator-associated pneumonia?
Critical Care volume 13, Article number: P292 (2009)
An intervention to improve oral hygiene (8-hourly OP cleaning/suctioning, toothbrushing and instillation of chlorhexidine gel) was commenced in one zone of an adult general ICU. Nursing staff in the rest of the ICU delivered standard oral hygiene (concurrent control). No other specific VAP prevention strategies were used in any patient. All patients on mechanical ventilation were reviewed daily for VAP using National Nosocomial Infections Surveillance criteria .
In a 4-month period, 71 patients were admitted to the intervention zone (Group A) and 189 patients were admitted to control beds (Group B). Table 1 summarises the results with values for age, APACHE II score and length of ICU stay shown as medians and interquartile ranges.
Use of an intervention to improve oral hygiene was associated with a reduction in the incidence of VAP.
